previous 32-bit X86 architecture applications, protect your previous investments; while Intel's itanium and itanium 2 series Processors require additional software or hardware for compatibility with previous 32-bit programs, so IA-32 (I .e. x86-32) x86-64 are x86, that is, Intel's 32-bit X86 architecture, such as Intel's 32-bit server Xeon (Xeon) processor series, AMD's full range, in addition, the full ra

same size. For example, a continuous page (4 K) can be divided into 32 128-byte objects.Allocation of small objects The size of each small object is mapped to one of the 170 allocable dimension classes. For example, 961 to 1024 bytes are normalized to 1024 bytes. The dimension classes are separated as follows: smaller sizes differ by 8 bytes, larger sizes differ by 16 bytes, and larger sizes differ by 32 bytes, and so on. Maximum interval (for dimensions> = ~ 2 K) is 256 bytes. A thread cache c

It will be better if it is changed to this: var mydiv = $ ("mydiv"); mydiv. parentnode. removechild (mydiv ). Fortunately, the DOM search for getelementbyid is relatively fast. If you replace it with getelementsbytagname, you should pay more attention to optimization. The jquery development team also reminded everyone t

The CPU freq tool is used to temporarily adjust the clock speed of the CPU. the CPU and the main board have power-saving technologies. If the CPU is working at a low load, the frequency is automatically reduced. If you need to temporarily set the clock speed and working mode, you can use cpufreq to manually adjust it. This mode will expire after restart. If you need to adjust it for a long time, modify/etc/sysconfig/cpuspeed. Www.2cto.com lsmod | grep "acpi_cpufreq" run the preceding command to

manufacturers in order to maintain compatibility with Intel's mainstream processor, all have to adopt this X86 architecture), but some extensions are made on this architecture to support 64-bitProgramTo further improve the computing performance of the processor. Compared to Intel's 64-bit server processor products, the x86-64 has the biggest advantage of being fully compatible with the previous 32-bit X86 architecture applications, protection is based on users' previous investments.

The performance of the motherboard With Different chipset designs is also different, and some of them are integrated into the motherboard, which needs to be carefully identified

The xw6200 and xw8200 are based on the intel e7525 (codenamed tumwater) chipset and support the latest 'nocona 'Xeon processors, the selling point of this processor is that it uses Intel's 64-bit extended memory technology (Intel em64t). In other words, this processor has the ability to run 64-bit code and use more memory, theoretically, up to TB of memory can be managed. It meets the needs of users in high-end PC environments, such as computer-aided

family: 15 Note: The CPU serial number produced by the CPU manufacturer can be used to determine which product the processor belongs.For example:The 6 series Intel processors include the Pentium Pro, Pentium II, Pentium II Xeon, Pentium III, and Pentium III Xeon processors.The 5th generation includes the Pentium processor and the Pentium processor using MMX technology.The F series intel processor includes

which the digital pulse signals in the CPU oscillate. In Intel's processor products, we can also see the example that the 1 GHz itanium chip can behave almost as fast as the 2.66 GHz Xeon/opteron chip, or 1.5 GHz itanium 2 is about as fast as 4 GHz Xeon/opteron. The computing speed of the CPU depends on the performance indicators of the CPU pipeline, bus, and other aspects.Of course, the clock speed is rel

bottleneck of the system. Such a persistent connection often does not send data, so it can also be viewed as an inactive connection. For the system, this kind of inactive connection does not occupy CPU and network resources, but only occupies the system memory. Therefore, we assume that the system can support the number of connections we want as long as the system memory is sufficient. Is that true? If this is the case, it is also a test for the kernel to maintain this large data structure. To
